I am looking to rebuild some mags, they worked fine with standard power springs, and for the most part still do. But I just think it's time to change springs, so my question is whether or not the wolf springs are worth it. Do they last longer than the G.I. springs? This is about the only possible benefit that I can see because you can't get much more reliable than 100% as I have had with my stock springs.

Input?

I guess my first question would be why swap out the springs if they are working?  USGI springs will last a long time.  Unless you shoot a high volume on a regular basis, there usually isn't a need to change the springs.  With that said, Wolff makes nice springs.  CP has standard USGI springs as well as chrome silicone springs at a lower price.  

Properly manufactured (standard USGI) stainless springs have worked extremely well for a long time.

i have some mags that have seen a lot of use and have purchased them a while back.  No issues with the springs.  Usually the failures to feed are attributed to the followers.  Once i reolaced the followers no more feeding problems and the mag runs like a champ.  (I use magpul followers with the stock springs)
